Morrissey's tour doesn't seem to be going as planned. Ongoing health issues, including a bleeding ulcer and Barrett's esophagus, have forced the singer to cancel a string of dates.

On Saturday, he added another cancellation to his growing list, this time a concert in San Francisco. A vague explanation was posted on his Facebook page.

"Due to Morrissey's medical condition, tonight's engagement at the Regency Ballroom in San Francisco will need to be rescheduled and will now take place on May 1. All tickets previously purchased for the Regency Ballroom show will be honored on the new date."
